My tip is not technical, I would say that you need to be honest with yourself and figure out what do you need, want and prefer because it is easy to get lost in the vast sea of options.
Take the time to ask what app/configuration would suit your need and feel free to ask for advice in something specific. Most often that not you will find someone that is like you and will share his experience saving you time, in any case there is a lot of learning involved. If you are the kind of person who read manuals and troubleshoots on their own it going to be easier. Otherwise be sure to pick a distro(if you are changing any time soon) that holds your hand.
Do not take opinions to hard, if it works for you… it works for you.
That said here is my take:

• If you do not plan to use the terminal at all then the most important decision you will take is your Desktop Environment. KDE will make you feel at home since you come from Windows.
• I suggest learning you distro’s package manager commands very well since you will be getting tons of new apps testing them and what not.
• There are universal packages called Flatpaks that should would on any distro, they are the easiest apps to install but I would suggest you use the corresponding package manager for loptimized ighter packages for your distro.
• Music Players that people like.
• Look for a backup tool like Timeshift to revert from a bad update or a mistake you have done.
• Obsidian is one of the best note taking apps there and Logseq its it FOSS counterpart.
• Try to look for apps that are Wayland compatible because every major DE is switching from Xorg to Wayland, this way the switch will be easier.
• Do not run any command you found from a random website.

Well, good luck in your journey!
